start level 1. Defeate all enemies but leave one neutral cell untouched. After that go get all the badges for "I am an insane rouge AI" and then come back and buy all the ship upgrades....
Simple game that I played a while back and got the badge. I started this and thought "I love this fast game with the nice relaxing jazz music. Play it again!"
A rather unique way to play a tower defense game. So many possible combinations for tower upgrade usage and no direct penalty for recycling/selling. This game has so much potential.
this game is like many other games i've played including dark orbit. All having the same concept and even the same currency that is hard to get unless you are willing to spend real cash to get it fast and put yourself on the top of the game...
Heat warning missions are no fun when the enemy can't repair themselves and you can. May as well make it into a defense not duel....all you have to do for those is sit and make a relatively light defense. Enemy fighters will do the job for you by exploding causing damage to enemy units.
